IMPROVEMENT IN PUMPS.

Specication forming part of Letters Patent No. 5 l,66, dated December 26, 1865.

lTo all whom it may concern:

Be it known that I, JOSEPH ALEXANDER BLOOM, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement on Water-Pumps; and I do hereby declare that Jthe following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specitication.

The annexed drawings represent a new and useful improvement on water pumps, especially useful for the navy, asit will draw more water with less labor in a shorter time than, any other ordinary pump ever would do, because it is double-acting, with powerful leverage.

Figures I and II represent two sections of said pump, the nature of which is as follows:

In Figs. I and 1I can be seen the piston-rod P It and the solid piston-head P Hin one cylinder. (The shaded part in the drawings represents the cylinder.) On the top is the reservoir It, with three valves, u n g. Below the reservoir is the partition S S, through which the piston-rod P R hermetically passes up and down. When the piston P H moves upward the bottom valve, m, will open.

In each side of the cylinder, FiO'. I, is one groove or canal, making two air-tight grooves or canals, C C, with their respective valves o lv u n. On the bottom part of the cylinderis the valve m. When the piston P H moves upward the bottom valve, m, will open and the side valves, Q: c, be closed until the piston P H descends. Then the bottom valve, m, will close, and the compressed water above it will force open the side valves, o c, and also the top valves, n u, through which the water enters the reservoir R.

Fig. II: This section shows a valve, o, in the groove or canal C, the opening m from the interior of the cylinder to the groove or canal C, also, it shows the top valve, g. When the piston descends a vacuum is created between the air-tight plate S S and the upper To ill this vacpart of the solid piston-head.

num, by the aid of the opening my the valve o will open, water will enter, and by repeated strokes ot' the piston will reach the reservoir R through the valve g. Thus by a double iniiux of water into the reservoir R it will cause a constant stream from the orifice o.

Fig. III is the top part and inside view of the reservoir R. n n g are the valves. u is a part of the top, in the shape of a cone, touching the cover of the reservoir It. Through this cone passes the piston-rod P It, preventing it from oxidation. The valves x x w and the elongated tubes (marked with dots and reaching nearly the cover of the reservoir) are intended as better adapted, should the reservoir be of considerable dimension.

Fig. IV represents a very powerful lever, with which the pump can easily be put and kept in operation; P, a part of a circle, with cogs inverted to its center. Fig. V shows the small cog-wheel g, part ot a larger cog-wheel, l, with handle to act upon parts a, and b, Fig. VI, and plate D, to which are strongly tixed the pivots p and p2. On the part b is placed the part P, and on that is put the part a, and kept together by the screws w u. To lit this lever together, begin by placing` the partP on the plate D, Fig. IV. Then the cog-wheel q over the pivot p', the part l over the pivot p2, which is the center to the lever-motion, and then screw the three parts P b a, together with the screws w w. The circular opening is for the parts P l) a to play freely on the pivot p. Fig. IV, on the pivot K, moves the part t, which is joined to the lifting-rod h 7L at the point y. The lever is xed to the pump by the plate D.

I claiml. The combination and arrangement of the parts R, C, P R, P H, and system of valves.

2. In combination therewith, the lever, constructed and operated substantially as described.

JOSEPH ALEXANDER BLOOM.
